IPC: C23G1/12
Filed: 1987-04-27
Abstract: PURPOSE:To dissolve an oxide film formed on the surface of a valve metal, and eliminate impurity such as chloride attaching to the surface, by washing, at a temperature of 40-80 deg.C, an electrode body subjected to a rough surface treatment with a water solution in which a specified amount of sulfamine acid and its salt are introduced. CONSTITUTION:After etching, electrode foils A-E, which are not washed, are extracted from the same part by sampling, and dipped in water solutions of sulfamine acid, at a temperature of 60 deg.C for 10 minutes. The concentration of each water solution is 0.1, 0.5, 1.0, 5.0 and 10.0% respectively. After dipping, remaining chloride on each electrode foil is checked, and, at the same time, electrostatic capacitances are measured. In the case of water solution of sulfamine acid whose concentration is larger than or equal to 0.5%, the specification for content of chloride, which is less than or equal to 0.00010mgCl<-1>/cm<3> is satisfied, so that the effect is verified. However, in the case of concentration larger than or equal to 10%, the capacitance decreases because the dissolving action of aluminum increases.

Abstract: PURPOSE: To maintain the safety in a manner to prevent from transmission of function to a function member even if a crank mechanism operates contingently, by a method wherein a vertical motion of a coupling shaft following a function of a crank coupling member is transmitted to the function member through an oval perfforation.  
     CONSTITUTION: If a body 1 is lowered in case a pile 27 is driven, the forward end of the pile 27 makes contact with a ground surface, and simultaneously, a forward end 13 of a coupling member 12 contacts a bottom surface 17 of a mating space part in a function member 14. A coupling shaft 15 makes contact with a bottom surface of an oval perforation 16, and a flange part 21 of the function member 14 presses a spring 22. With a motor M started, the pile 27 is driven without the production of noise resulting from the vertical movement of the crank coupling member 12 through the functon of the crank mechanism and through the existence of the spring 22. Even if the crank mechanism functions contingently, the coupling shaft 15 moves vertically in only the oval perforation 16, and the function is not transmitted to the function member 14. This enables maintaining of the safety.
